Abstract

The invention is a catheter (10) for use with a radioactive source (16) within the catheter (10) to irradiate a selected area of a blood vessel in combination with angioplasty procedures, to prevent restenosis of that area of the vessel. The catheter (10) has a guidewire channel (18) formed near its distal end to facilitate use of the cather (10) as a rapid exchange catheter, allowing insertion of the catheter (10) over a guidewire (20). The catheter (10) has a radiation lumen (14) with a sealed end to retain the radioactive source (16) within the catheter (10). The radiation lumen (14) is sufficiently longer than the guidewire channel (18), keeping the radiation source (16) segregated from the blood, allowing the use of a non-sterile radiation source. The catheter (10) can be provided with a balloon (22) or a set of wire loops (50) to center the radioactive source (16) radially within the blood vessel.
